Document Type and Number:
WIPO Patent Application WO/2021/106679
Kind Code:
A1
Abstract:
[Problem] To provide a pressure-sensitive adhesive composition capable of providing pressure-sensitive adhesive layers having excellent heat resistance, a pressure-sensitive adhesive layer and a pressure-sensitive adhesive sheet both obtained using the pressure-sensitive adhesive composition, and an optical laminate including the pressure-sensitive adhesive layer. [Solution] The pressure-sensitive adhesive composition comprises a resin, a crosslinking agent, a leveling agent, and a silane compound, wherein the leveling agent comprises a fluorochemical. In the pressure-sensitive adhesive composition, the content [parts by mass] of the silane compound is lower than the content [parts by mass] of the fluorochemical.
